If a fact is wrong, in your opinion, state the correct fact, preferably
with substantiation.

This is fascinating. Given that a fact is 'a done/made thing' (factum)
under what circumstances could it be wrong? To use definitions from
http://m-w.com : how can 'something that has actual occurrence' have 'the
state of being mistaken or incorrect'?

A general principle inferred from an anomalous fact is incorrect.

Mr Wagner, your statement - and my question which followed it - are about
a fact, not a principle or an inference.

It is unclear which fact you are referring to.

I am referring to the fact which is defined as 'a done/made thing'
('factum' or the result of 'facere').

Your question that followed it was this:


'Under conditions called 'one earth normal' and in the absence of opposing
forces this object was measured as falling with an acceleration caused by
gravity of 32ft/sec/sec.'

'No, that measurement was mistaken or incorrect. Here is the correct
fact:...'

Now... what would 'the correct fact' look like?

I was told in school that Galileo stood on top of the Tower of Pisa, dropped a cannon ball
and musket ball (bullet), observed they hit the ground at the same time This proved the
acceleration of gravity was invariant to mass.

Did you believe that?

There are a few problems with the story:

... The answer is simply wrong. The heavier ball lands first.

... Galileo never said they landed at the same time; he said the heavier ball lands first.

... The experiment probably never happened in the way described. Galileo was blind at the
time. Galileo never said it happened, one of his biographers did. Galileo described
similar experiments conducted in a lab decades earlier. Again, he reported the heavier
ball landed first.

Today I asked Russian and Yugoslavian colleagues whether they had been taught this fable.
Both said no. The Russian said they had been told that happens in a vacuum.

The first artificial vacuum was created by Torricelli in 1643, one year after Galileo's
death.

Technically the smaller ball initially pulls ahead because it has a lower coefficient of
drag. When it reaches terminal velocity, the heavier ball passes it. It is well known to
bicycle racers that a heavier rider will pass a lighter one when descending a hill, no
matter how streamlined the lighter one. The difference need be only 10-20 pounds.

That's what a correct fact looks like.
